There is no rank where he is over-performing, in fact he never leaves the top 10 worse heroes in terms of win-rate across all ranks.

His pick-rate is far from great either, across all ranks he is never in the top 10.

Basically what I am trying to say is that Hanzo in his current state is incredibly mediocre even by dps standards.
Sure he has a lot going for him and on paper I can understand why people would think he is OP but that is just forum Hanzo!

Even before the rework Hanzo on paper was OP, a lot of people wanted him nerfed even though he had the lowest win-rate in the entire game. It is the same story now, people see what Hanzo is potentially capable of and use it to justify calling for a nerf.

There is also a lot of hyperbole around Hanzo, he is not basically hitscan!!
His arrow projectile speed was increased by 16% and are still slower than Mei’s icicle while having a smaller hitbox as well.

His leap is not this amazing escape ability either, it travels all of 6m!
It is like trying to say that McCree’s roll is an amazing escape ability, it’s not! Hanzo’s leap allows him to get in and out of cover quickly but it will do absolutely nothing against a Tracer/Genji that jumps on you.

Hanzo is a broken hero. A good hero design gives the hero strengths and weaknesses. Hanzo has no weaknesses. He’s good at long range, good at mid range, and good at short range. He has above average mobility, good sustained damage, and great burst damage. There isn’t a single thing he doesn’t do well.

Is Soldier broken then? He even has sustain but I personally don’t think he is by any means OP.

Hanzo can do everything you just stated but it doesn’t mean that he is good at them!

He can be used at close range but he is still a squishy hero and will die incredibly quickly if you try to play him like this.
He can be used at long range but you will find that it is incredibly hard to hit anything consistently resulting in trash damage.
